The Chromosomes of Moniliformis dubius (Acanthocephala)
The Journal of Parasitology, 1965Squashes of testes and ovarian masses of Moniliformis dubius contained some gonial cells with mitotic metaphase configurations which are described and figured. The diploid chromosome number is eight in females and seven in males. An XO sex-determining mechanism is proposed, with the male heterogametic. During the first meiotic division of spermatocytes,

Los acantocéfalos constituyen un grupo monofilético de helmintos exclusivamente parásitos. Presentan una probóscide espinosa en el extremo anterior a la que le deben su nombre (del griego acantha: espina y kephale: cabeza) y mediante la cual se fijan a los tejidos de su hospedador. Son endoparásitos obligados del intestino de vertebrados y presentan un
